They have produced Acheulean stone tools and animal bones dating from between 200,000 and 400,000 years ago. It was not a settlement site, but instead seems to have been a waterside location where animals could be hunted or scavenged when they died by early humans. The humans used the tools to butcher the animals although many of the animal bones from the site represent kills by other carnivores.
One context, from Duinefontein 2, dated by optically stimulated luminescence dating to 270,000 BP contained ochre that must have been introduced to the site by people and which may have been used as body adornment. If so, it would represent some of the earliest evidence of an aesthetic sensibility in early peoples.
